Remember to open your Daily Rewards at your Tavern as you unlock them (a shiny chest will appear above your Tavern as you achieve your daily milestones) , as every even (2nd, 4th and 6th) chest contains a Barbarian Key.

Barbarian keys will automatically give Bonus Chests on Barbarian Camp Rallies. The Spoils of War mail you'll get at the end of a Barbarian Camp Rally will tell you if you had one, and thus whether or not you got a Barbarian Bonus Chest.

Remember to open the chests you receive from these Barbarian Camp or Nian Beast rallies. Just go to your items, select the chest or envelope and select Open. This will give you all the items inside.

Regularly click on your profile image to check the rewards medal to make sure you don't have any gold rewards left to collect.

Every 2 hours a gift from Merlin will appear near the Tavern/Daily Shipment dock. Be sure to click and collect it before the timer runs out! They currently arrive every whole even hour according to the UTC game clock. So, midnight UTC, 2 am UTC, 4 am UTC, etc.
